Hello

I'm feeling pretty ashamed to ask this, but i've been trying for pretty long now to no avail, and also searching perlmonks and google didn't point me to any hints. So I'm asking it here.

I have the following code, which should do nothing less than to transform pseudo-html line into real html. The problem where everything fails is in the final translation. The regex isn't "working" as expected. I guess it has something to do with $complete containing characters, that represent special chars to a regex (like / . [] etc).

any help on this would be greatly appreciated

#!/usr/bin/perl -w
use strict;

my $source = <<EOF;
[link title:Google]http://www.google.com[/link]
[link title:Altavista]http://www.altavista.com[/link]
[link title:perlmonks]http://www.perlmonks.com[/link]
[link title:and now something completely different]http://www.perlmonk
+s.com/index.pl?node_id=104944[/link]
EOF

my ($complete,$title,$url);
while ($source =~ /(\[link title:(.*?)\](.*?)\[\/link])/gi)
{
        $complete = $1;
        $title = $2;
        $url = $3;
        print "complete: $1\ntitle: $title\nurl: $url\n";
        $source =~ s/$complete/<a href='$url'>$title<\/a>/g || print "
+regex failed\n";
}
print $source."\n";
